IINrTnn STATES PATENT OFFICEa JOSEPH E. HOLMES, OF VASHINGTON, DISTRICT OF COLUMBIA.

COMBINATION REFRIGERATINGFSAFE.

SPECIFICATION forming part of Letters Patent No. 357,830, dated February l5` 1887.

Application filed August 31, 1886. Serial No. 212.320. (No model.)

T0 all wtom it may concern,.-

Be it known that I, J osEPH ELLrcorr HOLMES, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Combination Itefrigerating`- Safes; and I do hereby declare the following to be a full, clear, and exactdescription of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in refrigerating-safes used for the preservation of meats, fruits, and other perishable substances.

The object of my invention is to provide a refrigeratingsai'e having a gas-h older that can be lled without removal and without breaking its connection with the expansion-coil, and having a water or absorbing chamber constituting a base for the refrigerating-chamber that can be emptied and rciilled without removal, and it consists in the combination herein pointed out.-

In order that the nature and intent of my invention may be made more clear and better understood, reference is had/to the accompanying drawing, the iigure representing` a re frigerating-sai'e in perspective, partly in section, made in accordance with my invention.

Figures of reference indicate the different parts contained in the view.

l 1 1 indicate the base, which forms a reservoir for the absorbing liquids, (preferably made in metah) and constitutes the base of the structure, having formed on the top a iiange or socket, 2 2; 3 3 3, the refrigerating safe or chamber, mounted on the base 1 1 1 and seated in the socket 2 2, which can be hermetically sealed, forming a cover to the reservoir-base.

4E is the floor, and 5 thel door, ofthe safe.

6 6 is a shelf dividing ol'fa small portion of the upper part of the safe, for a purpose hereinafter explained.

7 7 is thc reservoir to contain the volatile gases under pressure, occupying the small chamber formed by the shelf 6 G. This reservoir is preferably made of strong metallic pipe bent or formed in the manner shown in t-he drawing, or in a coil having a capacity to contain a suiiicient amount of compressed or liquefied gas for any given number of days that may be required 5 or it may be in the form of narrow cylindrical holders having a connection with the receiving and discharge pipes.

8 8 is the refrigeratingcoil as ordinarily arranged in the top of the main chamber of the safe, communicating with the reservoir 7 7 by.

tion; but I prefer to use the one described in my application No. 209,711, iiled July 31, 18

11 is a vertical pipe connecting the refrig erating-coil S 8 with a distributer, 12, arranged in the reservoir-base 1, fordischarging the eX- panded gases under the surface of the absorbing liquid 13 after it has performed its office in the refrigeratingchamber.

14 is a valve by which connection is made for supplying the reservoir 7 7 with compressed or liquefied gases, and 15 a valve for filling or discharging the base 1 1.

I am aware that refrigerating cars and vessels having portable gasholders, rel`rigeratingcoils, and absorbing vessels are well known, and my claim is therefore limited to the novel combination hereinafter pointed ont.

I claim- The described refrigerating-safe, having a holder, 7, for condensed gases, an inlet-pipe, 14, furnished with valve and coupling outside of the safe, and connected to one end of said holder, au expansion-coil, 8, connected to the other end ofsaid holder, a governor interposed between the holder and enpansion-coil,` a water tank 0r absorber, l, constituting a base for the safe, an outlet-pipe, 15, from the absorber, provided with a valve and coupling outside the safe, and a distributer connecting the absorber with the expansion-coil, the gas-holder, expansion-coil, governor, absorbing-chamber, distributer, and connections being all inclosed in and xtures of the safe, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH E. HOLMES.
